I'm sure there are some pills that can make it go away.
Or... You could just say fuck it all and let things happen as they will. I've learned to do that after only two years of university. If I won't get that assignment finished on time, well... fuck it. I'll hand in what I've got, take my bruises and try to learn from my experiences to see what I can do better next time.
Now, I realize that that attitude won't cut it in a work environment, but a lot of companies have facilities/programs for stress, etc.
If it's your family that's causing the stress, stop seeing them. Worked for my parents and half my relatives. :/
